CHARLES DOBBS, OF DALLA S, TEXAS.

CAR-COUPLING.

Specification of Letters Patent.

Patented July e, 190e.

Application filled November 25, 1908. Serial No. 464,475.

To all 'whom it may concern:

Be 1t known that l, CHARLES Donne, a

` citizen of the United States, residing; at

Dallas, in the county of l)allas-a.nd State of Texas, have invented new and useful lmprovements 1n Car-Couplings, of which the follwing 1s a specification,

This invention relates to car couplings, the object of the invention being to provide a simple and eil'eetive device of this clniractcr by which two cars can be separably connected together in a secure manner.

In the drawings accornpanying` and forn1- insr part of this specification l show in detail one advantageous form of embodiment of the invention which, to enable those skilled in the art to practice the same, will loe set forth at length 1n the following description, while the novelty of the invention will be included in the claims succeeding: said description.

lleiicrring;` to said drawings: Figure 1 is al perspective view of a car coupling' involving` my invention and showing the saine connected with a car. Fig'. 2 is a side elevation of said coupling. Fig. 3 is a top plan view of the coupling, the pin-carrier being' shown in horizontal section. Fig. 4 is a longitudinal view partly in section. Fig. 5 is a detail sectional view lllereinafter more particularly described.' Fig. 6 is a perspective viewof a locking slide or detent, Fig. 7 is a side elcvation1 of the Inn-carrier. Fig. 8 is a perspective view of the link.

Like characters refer to like parts througla out the several figures;

-ln Fig. 1 of the drawings I have shown the end portion of a car as 2 with which my coupling may be connected in any desirable manner, said coupling including,r in its con- ,struction a chambered draw-head as 3 the chamber of which is denoted by 4. The forward portion of the lower wall of the chamber 4 has a downwardly and forwardly inclined link-liftingr face as 5.

The pin of the coupling is designated by 6 and it yis connected in some desirable way to a pin-carrier as 7. The pin-carrier is represented as consisting' of an open or substantially skeleton-like franie'the side bars of which are adapted to straddle the drawhead, the latter having notches as 8 to rc- .ceive the vertically-disposed side bars of said pin-'carrier 7, by virtue of which trippingr or swmgmg movement of said pm-carrier is prevented. In the present case, the upper end or head portion of the pin 6 is swiveled ,l to the upper cross-bar of said pin-carrier. To the pin-carrier or to the upper portion of the pin a chain as 9 may be connected, said chain being illustrated as also connected to a crank-arm as 10 fastened to the rock-shaft 11 supported by suitable bearings on the end of the car 2, said shaft also having attached thereto a hand-lever as 12 by which the shaft can be operated to raise theI pin-carricr 7 and thereby also move the pin (5 out of coperative relation with a link as 13.

The chain 9 may be provided, with an upward continuation as 1.4 adapted to extend lto thereof of the car, whereby the pin-car rier can be elevated for uiicouplinepurposes from said roof, this being' of particular advantage when the car equipped with the coupling is in motion. rlhe pin 6 has a n'lovement through a perforation or hole as 15 in the upper side of the draw-head $3 and it may be provided with a hnil'er as 1G adailited to strike the upper side of Isaid draw-head when the pin passes.throuih one of the openings in Ithe link 13, as indicated in Fig. /.l. This buffer `1.6 may he of rubber or any other suitable mate-rial.

lf desired, the fpin carrier 7 may be equipped with a handle as 17 constitutin; in the present case a continuation of the lower cross-bar thereof and by Agraspingwhich said pin-carrier can be elevated. The link 1b will, as will be clear, have two perforations or holes through it, through which pins as 6 of opposite couplers are adapted to pass, and the pin 6 is shown in Fig'. 4c as extended through one lof the perforations of the link 1.3.

In F 1 and? the pin-carricr 7 and pin (i are represented as being' up and they are maintained in this position in a positive manner by a detent-such as that denoted in a general vway by 1.8 and shown in detail in Fig. 6.

The detcn t or lockingI device 18 is shown as supported for slidingl movement by a bracket as 1l) supported by the draw-head 3 at one side and at or near the top thereof, the bracket 1.9 beiner of substantially right-angular form in cross section, as shown best in Fig'. .5. The sliding detent or Ilocking` device 18 has a forward extension as 20 of less width than the body of said detent and it terminates in an inwardly extending projection 2l which has a play in a groove or channel as 22 formed near the outer or forward end of the draw-head 3. The detent 18 is provided with a rearward extension 23 of somewln'it zontal JIpath. The rear or inner end .of the body o the detent 18 and the shoulder or inner face of the projection 21 are adapted to limit the inward or rearward movement of the detent 18, the projection 21 and the body of the detent for this purposel enga ing the pin-carrier 7 and eye 24, respective y. On the upper side of the detent 18 I have shown an inwardly extending flange as 25 equipped with an upwardly rejecting in as 26 constituting a handle iiy which tie said detent 18 can be readil manipulated. The for- .Ward end of this ange 25 is beveled as at 27 and this beveled end 27 constitutes the operative or effective portion of the detent 18, being cooperative with a notch as 28 in one of the side bars of the skeleton-like pin-carrier 7.

lIn Figs. 1 and 2 the pin 6 and its carrier 7 are shown as up, the detent 18 being at this time in its forward position and the beveled portion 27 being seated in the notch 28 so that the detent will hold the pin and pin-ear" rier up; at this time the extension 20 of the detent will be forward of the front or outer face of the draw-head 3 where it can be engaged by the draw-heady of a companion coupling mounted on a car moving toward the first-mentioned draw-head. When the moving draw-head has nearly approached the stationary draw-head, the moving drawhead will strike the forward end of the extension 20 and, on the continuation of such movement, will move the detent 18 inwardly or rearwardly and will carry the beveled portion 27 out of the notch 28 and will thereby release automatically the pin-carrier 7 so that the pin 6 can then pass through the perforation, hole, or o ening in the link 13 which, in the meantime, as been positioned within the stationary draw-head.

In Fig. 4 the pin 6 is shown as projected through one of the openings of the link 13, the latter hanging at a downward angle from the pin. movingV toward a stationary draw-head. When the free portion of the link 13 strikes the inclined face 5 of the com anion drawhead, said inclined surface Wil on the Inotion of the moving draw-head, cause the link to assume a horizontal position and, at about It will be assumed that this link is the time this takes place, the pin on the sta; tionary draw-head is released t0 effect the coupling. The Bange 25 overlies and slides u on the upper surface of the .draw-head 3.

hen the two cars are coupled there is ample provision for vertical and side motion thereof.

What I claim is:

1. A car coupling comprising a chambered draw-head, a coupling-pin, a carrier for said coupling pin, operatively associated with'said draw-head, and a slidable detent atene side of the upper portionof the draw-head and provided with an inwardly projecting portion, the pin-carrier having a notch to receive the inwardly projectingportion of said detent, and the latter, when in its operative position, having an extension projecting beyond the forward or outer end of said drawhead.

2. In acar coupling, a drawehead, a coupling pin, a movable carrier for the coupling pin, an angular bracket carried by the drawhead, and a slidable detent supported by said bracket and having a flange overlying the top of the draw-head, the pin-carrier having a notch and the flange having a beveled portion to enter said notch to'hold the pin-carrier and pin in elevated positions.

3. In a car coupling, a draw-head providedwith an angular bracket, a coupling pin, a pin-carrier movably associated with said draw-head, a detent slidably supported by said bracket 'and adapted to engage the pin-carrier to hold the latter and the pin in elevated positions, saiddetent having a for ward extension adapted, when the detent is in its operative position, to extend beyond the forward or outer end of the draw-head, a handle on the detent, and a handle on the pin-carrier.

4. ln a car coupling, adraw-head, a eoupling pin, a pin-carrier movably associated with said draw-head, and a sliding detent provided with a frame overlying the top of the drawel'iead, the pin-carrier having a notch, and the forward portion of said fiange being adapted to enter said notch to hold the' pin-carrier and pin in their elevated positions.

In testimony whereof I have-hereunto set my hand in presence of two subscribing witnesses.
